Building Confidence

[FfNJGTFO]

And yet another Update. Had an excellent day on the precision range. Got a really nice grouping on the RPR. I just have to adjust a smidge more and I'll be right on target. But I also have to learn to control my own movements as well because no matter how accurate you are with your rifle, you also must have accuracy in how you hold it. And I'm complicating things by learning how to shoot left handed (I'm right handed, left eye dominant).


The AR is working perfectly and the bolt catch held after I emptied a mag. It is 100% now. I just have to keep it cleaned and oiled. And I have to make some minor adjustments in re: zeroing it in. At least, I'm on paper and very close to zero. I think one more range session should do it.



Thanks all. I'll most likely start the 2nd AR build in early 2022.

Quick Question: What are you all recommending for "Frangible 5.56?" If I'm going to put either this build or "Build #2 (comming in 2022) into the HD plan, I'm not going to be able to use "Green Tip" for that So, I'm looking for some good Frangible 5.56 that will get the job done without overdoing it.


Any recommendations?

What do you mean by "HD plan?" Home Defense? If so, you don't need frangible. Get good hollow point ammo and stay with 55 grain.
We did some extensive testing on .223/5.56 ammo when we switched from the MP5's to M4's. Everyone was afraid of over penetration.
What we learned, and it's going to sound counter intuitive, is the 9mm was over penetrating, more than the 5.56.
The heavier 9mm was plowing through 2 X 4's, sheet rock and many obstacles, while the lighter .223 was more susceptible to deflection as well as slowing down and being stopped by solid obstacles.
If you were to fire a 9 vs 5.56 outside then yes, the 5.56 would go farther. What we discovered, and this was supported by the sate AG's office as well, within most interiors the 9mm was penetrating more than the .223/5.56.


Now me personally, I have handguns for home defense, but my go to is a pistol caliber carbine, a HK USC. It's loaded with Federal 230 grain Hydroshoks.

My 5.56 load is 55 grain soft points made for varmint hunting. No worries about overpenetration with those.
But that's for exterior home defense, not for indoor home defense. For indoors I have a 45 ACP Hi-Point carbine loaded with 230 grain XTPs.

Jake and I shot one round of 5.56 at our backyard backstop. It went through a 4x4 post, a pine tree, and took off through the scrub to parts unknown. And it was a hollowpoint. Just sayin...

Never said they wouldn't penetrate. Just the odds were better than a 9 coming out of carbine.
Also, I forgot to add, I don't believe frangible was designed for self defense. More for using in indoor ranges and/or on steel. Also, lead free.

Hollowpoints need soft tissue to expand. I had a Sierra 165 gr hollow point boat tail go through a tree and kill a deer on the other side of the tree. The deer was moving and stepped behind the tree trunk just as I pulled the trigger. I centered the tree trunk and the bullet went straight through and then flew true another 20 yards before hitting the deer. I found the bullet hole. A soft point would have expanded inside the tree and disintegrated.
